Question

Find the mean proportional of : (1)8, 18 (ii) 25,4​

Answer 1

Answer:

To find the mean proportional, first multiply the two given numbers together, then find the square root out of their product. Then the answer will be the mean proportional.

18,8

$= > 8 \times 18$

$= 144$

$= \sqrt{144}$

$= 12$

$\therefore$ The mean proportional of 8 and 18 is 12

25,4

$= > 25 \times 4$

$= 100$

$= \sqrt{100}$

$= 10$

$\therefore$ The mean proportional of 25 and 4 is 100

Answer 2

$\Huge\mathbf\blue{Hello\; \;Mate}$

To find the mean proportional of any digit we have to multiply them together and then we'll find square root of the answer.

Here We Go⤵

1. 8 and 18

$\Longrightarrow$ 8×18

$\Longrightarrow$ 144

$\Longrightarrow \: \sqrt{144}$

$\Longrightarrow 12$

$\therefore$ 12 is the mean proportional of 8 and 18.

2. 25 and 4

$\Longrightarrow$ 25×4

$\Longrightarrow$ 100

$\Longrightarrow$ $\sqrt{100}$

$\Longrightarrow$ 10

$\therefore$ 10 is the mean proportional of 4 and 25.
